Be it known that I, EMILE GQBBI, of 45 Rue Jacob, 1n the cityof'Paris, Re ublic of 'France, engineer, have. invented niprovements in Apparatus for Filtering Liquids and Fluids, of which the following is'a full, clear, and exact description.

This invention relates to apparatus for the filtering of liquids or fluids constituted by a number of superposed non-permeable mem bers between which the liquid, which for example it may be desired to filter passes. To this end the aforesaid members present juxtaposed surfaces held more or. less in intimate contact with-one another by means capable of being adjusted according to whether it be desired to regulate the degree of filtration or the flow of the li uid or fluid, or-to facilitate the return flow 0 the filtered liquid, when it is. desired to cleanse the filtering members and the remainder of the apparatus of which they form a part. a The aforesaid members may be arranged so as to filter liquids. passing from without to within or vice versa.

The. invention will be described with reference to the accompanying drawings wherein: Flgures 1 and 2 show 1n cross section and plan two halves of a filtering member in the 1 bodying my invention; Fig. 11 shows still another form in vertical section and in plan view; Fi 12 1s a vertical section of another form of tering member; Fig-13 is a vertical section of still another form; and Fig. 14'

shows a further form of construction in vertical section and in plan view. I

As is shown in the drawings the filtering apparatus consists essentially of non-permeable members presenting' uxtaposed surfaces designed soas to enable them to be superimposed more or less in intimate contact one'upon' another by a method of. fixing specially adapted for this purpose.

According to the arrangement shown in the drawings, Figs. 1, 2 3- and 4, the filtering members comprise dishes a and I) placed one above the other in such manner that the liquid or fluid to be purified can penetrate to the interior of the chamber formed by the juxtaposition of the dishes through apertures c, Fi 3. The two dishes a and b are connected y means of a neck or collar (1 on the lower dish of each pair. Which extends into a central a erture e in the upper dish of the next succee ing pair.

Any number of filtering members threaded upon a rod f of star-shaped cross section may form a battery which is received within a'cylindrical receptacle 9. This receptacle is provided at its lower part with a pocket It having an inlet t for the entrance of the liquid to be purified, and having attached to it a valve chamber 1' with a screw-down valve and wheel is and discharge pipe I. At its upper part said cylindrica with a sleeve m having a shoulder n between which and a nut p on rod f a retracting spring 0 is confined, the rod f being screw-threaded. as at f to afford means for adj'usti the proximity to one another of successive tering chambers.

receptacle is fitted A neck g to which the receiver r of the I filtered liquid is attached is mounted above sleeve m, and a tap s for drawing off the liquid is'secured to said neck g. The'receiver is provided at top with means for the admission of air consisting of a hollow stopper t containing cotton wool 11. soaked in a sterilizing agent. The liquid entering through inlet i 'passes throu h valve chamber 7' and aper- The purified liquid in the'receiver then exerts pressure from within the urifying chambers 1n pro ortion to its heig t tending to separate t e chambers and to expand spring 0 so that the 'urified water flows downwards carrying with it through pipe Z all ,the imurities deposited on the surfacesfof the dishes and on the other parts of the apparatus.

The purifying members shown in 'the drawings at Fig. 8 are annular and their.

function is identical with that of the members described above, but the flow of liquid isgreater. v

By inter osing a suitable disk. between each pair 0 -dishes increased In Fig. 9, each filtering element comprises two concentric elastic rings, and each of these rings is composed of an upper concave "sec-- tion a and a lower concave section 6, connected by tubular necks.'

In Fig. 10 I employ disks 1 having at their inner and outer edges feet or projections by means of which one disk rests on the one below; the disks are superposed or stacked around a central vertical pipe 2 which is perforated and servesas a conduit for the purified liquid. 1

In Fig. 11 I have shown two concentric series of disks 3, 3' of the same characteras those of Fig. 10; the inner disks3 enga e the dischar e pipe, the outer ones 3 are ar eiso as to eave a space between their inner disk and the outer disk of each layer or tier.

In the construction illustrated by Fig. 1 2,

I the disks 4, instead of having downward projections at their inner and outer edges, are provided with flanges projecting upwardly and downwardly at theirouter edges, the upward flange of one diskjfteing in contact with the downward flange of the next disk a ove.

In 13, disks 6 of the same construction as shown in Fig. 12, are combined with an outer set of disks "or rings 6. having upward and downwardflanges both at their inner and at their outer edges.

In each of the constructions'represented the flow of the liquid is,

in Figs. 10 to 13 inclusive, springs are interpose between adj acent disks or rings so that when the nut at the end of the series is loosened, adjacent disks will be-forced apart .bythesprin s located between them, so as to'allow the ter to be cleaned by passing a clean liquid therethrough in the direction apposite to that of the'fiow during filtration. ese springs are designated as 5 1n Figs. 10 and 11, and as 5' in Fi s. 12 and 13.

In Fig. 14 the dis have a number of small tongues f serving as springs and roduced by stamping u the metal, the isks being further provide below with flanges as shown.

Claim:

1. A filter comprising a series of filtering members held together ieldingly so that they may move apart slig tly when the flow of the fluid is reversed to clean the filter.

2. A filter comprising a series of filter elements and elastic means for normally pressing said elements together.
